Description

Technical Field

[0001] This utility model relates to the field of rope embroidery technology, and in particular to a rope embroidery device and embroidery machine that integrates rope clamping and cutting. Background Technology

[0002] In rope embroidery devices, a rope clamping mechanism is usually installed at the rope cutting mechanism to clamp the rope and prevent it from springing back and detaching from the sleeve when the rope is cut by the cutting mechanism. This leaves excess rope for use in the next rope embroidery pattern. Existing rope clamping mechanisms are usually elastic bodies located at the rope cutting mechanism, typically spring plates acting as clamps to hold the rope. However, for very thick ropes, the spring plates are prone to bending or failing to clamp securely; for very thin ropes, they may not be clamped at all or may detach from the clamping plate.

[0003] In addition, the existing rope clamping and rope cutting are driven separately by two different drive mechanisms, which is complex in structure and occupies a lot of space. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides a rope embroidery device and embroidery machine that integrates rope clamping and cutting. It uses a drive mechanism to drive the rope clamping and cutting, and can precisely adjust the clamping degree according to the thickness of the rope, resulting in good clamping effect. It adopts a single drive mechanism, has a simple structure, and is low in cost.

[0005] The technical solution adopted is as follows:

[0006] A rope embroidery device integrating rope clamping and cutting includes a rope clamping mechanism and a rope cutting mechanism correspondingly mounted on a mounting plate and cooperating with each other. It also includes a drive mechanism that can simultaneously drive the rope clamping mechanism and the rope cutting mechanism. The drive mechanism includes a drive motor, a drive component that drives the rope clamping mechanism and the rope cutting mechanism to open or close, and a transmission component disposed between the drive motor and the drive component.

[0007] Furthermore, the positions of the rope clamping mechanism and the rope cutting mechanism are arranged in a corresponding manner, so that the rope clamping mechanism completes the rope clamping first and then the rope cutting mechanism cuts the rope, or at least the rope is cut at the instant the rope clamping mechanism clamps the rope.

[0008] Furthermore, the rope clamping mechanism includes a first clamping plate mounted on the mounting plate and a second clamping plate rotatably mounted on the mounting plate.

[0009] Furthermore, the mating surfaces of the second clamping plate and the first clamping plate are provided with teeth; the first clamping plate is mounted on the mounting plate via a mounting shaft, and a second return spring for positioning the first clamping plate is provided on the mounting shaft.

[0010] Furthermore, the second return spring is a torsion spring.

[0011] Furthermore, the rope-cutting mechanism includes a fixed blade fixed to the mounting plate and a movable blade rotatably mounted on the mounting plate.

[0012] Furthermore, the second clamping plate of the rope clamping mechanism and the moving blade of the rope cutting mechanism are mounted on the same rotating shaft. The rotating shaft is rotatably mounted on the mounting plate. The second clamping plate is connected to the rotating shaft through a driving component, and the moving blade is connected to the rotating shaft through a moving blade holder.

[0013] Furthermore, the transmission assembly includes a connecting rod on the drive motor, a transmission rod between the connecting rod and the drive member, an extension rod connected to the transmission rod on the drive member, and a universal wheel at at least one end of the transmission rod.

[0014] Furthermore, the motor mounting plate of the drive motor is provided with a limiting post to restrict the rotation of the drive arm, and a first return spring is provided between the motor mounting plate of the drive motor and the extension rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides a rope embroidery device integrating rope clamping and cutting, and an embroidery machine equipped with the device. The rope embroidery device includes a rope clamping mechanism and a rope cutting mechanism, which are driven by the same drive mechanism. The drive mechanism includes a drive motor, a second clamping plate for driving the rope clamping mechanism and a drive component for rotating the moving blade of the rope cutting mechanism, and a transmission assembly located between the drive motor and the drive component. By using a motor to drive the clamping plate, the distance between the two clamping plates can be precisely controlled according to the thickness of the rope, resulting in better rope clamping effect and wider applicability. Compared with the elastomers in existing technologies, it is less prone to deformation and detachment.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] refer to Figure 1-5 A rope embroidery device and embroidery machine integrating rope clamping and cutting includes a rope clamping mechanism 1 and a rope cutting mechanism 2 correspondingly mounted on a mounting plate 3 and cooperating with each other. It also includes a drive mechanism 4 that can simultaneously drive the rope clamping mechanism and the rope cutting mechanism. The drive mechanism 4 includes a drive motor 401, a drive member 402 that drives the rope clamping mechanism and the rope cutting mechanism to open or close, and a transmission component 403 disposed between the drive motor 401 and the drive member 402.

[0024] The transmission assembly 403 includes a connecting rod 4031 mounted on the drive motor 401 and a transmission rod 4032 located between the connecting rod 4031 and the drive member 402. The drive member 403 has an extension rod 8 connected to the transmission rod 4032. At least one end of the transmission rod 4032 is provided with a caster wheel 17. Preferably, the present invention provides caster wheels 17 at both ends of the transmission rod 4032 for better driving effect. The drive motor 401 drives the connecting rod 4031 to swing, which in turn drives the drive member 403 to swing via the transmission rod 4032.

[0025] Preferably, the motor mounting plate 9 of the drive motor 401 is provided with a limiting post 10 to restrict the rotation of the connecting rod 4031, thereby controlling the swing amplitude of the connecting rod 4031. A first return spring 11 is provided between the motor mounting plate 9 of the drive motor 401 and the extension rod 8, which is used to cooperate with the drive motor auxiliary transmission rod 4032 to reset, resulting in a faster reset speed. In this embodiment, preferably, the first return spring 11 is a tension spring.

[0026] The rope clamping mechanism 1 includes a first clamping plate 101 fixedly mounted on the mounting plate 3 and a second clamping plate 102 rotatably mounted on the mounting plate. The rope cutting mechanism 2 includes a fixed blade 201 fixed on the mounting plate 3 and a movable blade 202 rotatably mounted on the mounting plate 3. The first clamping plate 101 is mounted on the mounting plate 3 via a mounting shaft, and a second return spring 16 is provided on the mounting shaft to position the first clamping plate 101. The second return spring 16 is provided on the mounting shaft, with one end of the second return spring 16 located on the first clamping plate 101 and the other end located on the mounting plate 3. The second return spring 16 is used to position the first clamping plate 101 and drive the first clamping plate 101, so that the first clamping plate 101 and the second clamping plate 102 can better cooperate to clamp the rope. When the first clamping plate 101 and the first clamping plate 102 are used to clamp the rope, if the first clamping plate 101 deforms, it can be reset by the second return spring 16 to return to the initial position, ensuring the relative cooperation between the first and second clamping plates and the clamping state of the rope. The position of the first clamping plate 101 can be changed by rotating the second return spring, that is, the position of the first clamping plate relative to the second clamping plate can be adjusted to facilitate better cooperation between the first and second clamping plates. The position can be adjusted to suit ropes of different thicknesses. Preferably, the second return spring 16 is a torsion spring.

[0027] The second clamping plate 102 and the moving blade 202 are mounted on the same rotating shaft 5, which is rotatably mounted on the mounting plate 3. A bearing is provided between the rotating shaft and the mounting plate 3, allowing it to rotate relative to the mounting plate 3. The rotation of the rotating shaft 5 simultaneously drives the second clamping plate 102 and the moving blade 202 to rotate.

[0028] The second clamping plate 102 is connected to the rotating shaft 5 via a driving component 403, and the moving blade 202 is connected to the rotating shaft 5 via a moving blade holder 7. That is, the driving component 403 swings to drive the rotating shaft 5 to rotate, thereby driving the second clamping plate 102 and the moving blade holder 7 to rotate, i.e., the second clamping plate and the moving blade rotate simultaneously.

[0029] The rope clamping mechanism 1 and the rope cutting mechanism 2 are positioned correspondingly. To prevent the rope from springing back and detaching, the rope clamping mechanism must clamp the rope first, and then the rope cutting mechanism must cut the rope, or at least the rope must be cut at the instant the rope clamps. This can be achieved by making the distance between the first and second clamping plates smaller than the distance between the fixed and moving blades, meaning the range of motion for clamping the rope between the first and second clamping plates is smaller than the range of motion for cutting the rope between the fixed and moving blades. Thus, when the drive mechanism drives the second clamping plate and the moving blade to rotate simultaneously, the second clamping plate contacts the rope first and clamps it, and then the moving and fixed blades contact the rope to cut it, or the rope is cut at the instant it is clamped.

[0030] The second clamping plate 102 has teeth 6 on its mating surface with the first clamping plate. The teeth 6 increase friction, allowing the rope to be better secured between the first and second clamping plates, making it less likely to fall off the clamping plates and improving the rope clamping effect.

[0031] The second clamping plate 102 is rotated by the drive mechanism 4, allowing the distance between the first and second clamping plates to be adjusted according to the rope thickness. This adapts to ropes of varying thicknesses, broadening its applicability. Compared to the spring plates used in existing technologies, the clamping plates are less prone to deformation, are movable, and allow for precise distance control, resulting in better rope clamping and preventing the rope from slipping off. Using the same drive mechanism 4 to drive both the clamping and cutting of the rope simplifies the structure, reduces the number of drive components, saves costs, and occupies less space.

[0032] This utility model also protects an embroidery machine, including a machine head 12 and a rope embroidery device disposed on the machine head 12. The rope embroidery device is the rope embroidery device described in any of the above-described embodiments. A lifting mechanism 13 and a sliding structure 14 are provided between the rope embroidery device and the machine head 12.

[0033] The machine head 12 is provided with a connecting plate 15, and the sliding structure 14 consists of a slide rail 1401 on the connecting plate 15 and a slider 1402 on the drive mechanism 4. The rope embroidery device can slide relative to the machine head 12 to enter the working position to cut and clamp the rope, or retreat away from the working position.

[0034] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
